I have a big problem with opening ports in this router. Something that I've never had in the past. I use Sky ISP with the Netgear DGN2200.
Basically whatever port I try to open. I get this Failure error message. I need to open some ports for Steam and Games for Windows Live where the NAT is stricted. But I get this error...
"Failure The specified port(s) are being used by other configurations. Please check your configurations of Remote Management, Port forwarding, Port Triggering, UPnP Port Mapping table, RIP, and Internet connection type This screen will automatically return to the previous screen in a few seconds..."
I cannot open any of the ports. I never had this issue before. I factory resetted the router. I even upgraded to the latest firmware and even downgraded. Nothing works.
The only solution that works is by assigning a DMZ Server where it will allow all ports to be opened at an assigned Static IP address. But I read that this is not a practical solution. Not to mention this will not help with opening all the other ports in the other computers.
Therefore I want to be able to open the ports in the normal procedure. But the Netgear router simply won't allow that to happen. It's a failure every single time with no avail.
Has anyone found a solution to this problem?
